Definitions

  • the Camsizer® set-up employs a dynamic imaging technique, rather than actual 'physical' sieving of the particles.
  • Samples are dispersed by pressurised air and passed through a gap illuminated by two bright, pulsed LED light sources.
  • the images of the dispersed particles are then recorded by two digital cameras and analysed for size and shape in order to determine a variety of length and width descriptors for the particles, as required e.g. by ISO norm 13322-2 (on particle size analysis via dynamic imaging); e.g. the width of the particle, i.e.
  • the pharmaceutical composition of the invention it is in principle of little relevance whether the target particle sizes are achieved via granulation or other techniques (e.g. optimized crystallisation techniques) and/or whether the raw material already fulfils the target size requirements or needs to be classified in sieving steps first. Nonetheless, since the composition is adapted for direct oral administration, there may be further preferences, for instance with regard to upper particle size limits and/or particle shapes, which may guide the choice of specific ibuprofen and/or excipient grades as will be detailed below.
  • the mean particle size of the ibuprofen particles ranges from about 200 ⁇ m to about 400 ⁇ m. Optionally, it is in the range from about 230 ⁇ m to about 370 ⁇ m, or from about 260 ⁇ m to about 340 ⁇ m.
  • the median particle size (D50) falls within the same ranges. In a specific embodiment, the mean particle size falls within the range of ⁇ 5 % of the median particle size (D50) or vice versa, or even within the range of ⁇ 3 %. This is typically an indicator of a narrow particle size distribution (PSD) and thus helps to avoid batches containing too much fine powder and/or too many larger particles despite seemingly suitable mean values of e.g. 250 ⁇ m.
  • PSD narrow particle size distribution
  • the aspect ratio (AR), also sometimes referred to as width/length ratio or breadth/length-ratio, is a shape factor used in image analysis which is defined e.g. as the ratio of the particle's width to the maximum Feret diameter (X c min /X Fe max ).
  • ISO 9276-6 norm defines the aspect ratio (AR) as the ratio between the minimum and maximum Feret diameters (X Fe min /X Fe max ).
  • the vice versa definition of the aspect ratio i.e. 1/AR
  • AR-values of more than about 0.714, 0.769, 0.833, 0.909, or 0.952 would thus translate to 1/AR-values of less than about 1.4, or less than about 1.3, or less than about 1.2, or less than about 1.1, or less than about 1.05.
  • a spherical particle would have the aspect ratio of 1.0.
  • the aspect ratio is determined by automated image analysis; for instance, the Camsizer® XT device described above for the determination of the particle size distribution also calculates the aspect ratio and reports it as the volume based mean b/l 3 for all particle classes (as shown e.g. in Table 2). Therefore, in one of the preferred embodiments, the aspect ratio is determined using the Camsizer® XT device.
  • the spheroidal or spherical shape of the ibuprofen particles also improves the flow properties of the compositions. This is relevant for manufacture, in particular the filling of the powder composition into the primary packaging units such as sachets. At the same time, the spheroidal or spherical shape enhances the withdrawal of the composition from these units by the patient for administration.
  • the use of polymers which are water-insoluble or poorly water-soluble and/or which do not swell, gel, or thicken at body temperature when contacted with saliva should be limited to ⁇ 15 wt.-%, or ⁇ 10 wt.-%, or ⁇ 5 wt.-% based on the total weight of the pharmaceutical composition. Since the majority of such excipients exhibiting poor aqueous solubility - including e.g.
  • the pharmaceutical composition may comprise from about 0.5 wt.-% to about 20 wt.-% of the hydrophilic polymer, or from about 0.8 wt.-% to about 10 wt.-%, or from about 1 wt.-% to about 8 wt.-%, e.g. about 5 wt.-% or about 6 wt.-%.
  • These values are particularly useful for pregelatinised starch, xanthan gum, and carmellose-sodium; in particular pregelatinised starch.
  • the amount of the hydrophilic polymer may be adjusted depending on the selection of the specific polymer, keeping in mind e.g. its gel formation strength, temperature and/or ion responsiveness etc. For instance, the gel formation strength of Blanose® and xanthan gums is commonly more pronounced than that of Lycatab® PGS; hence less Blanose® and/or xanthan gum needs to be added to formulations in comparison to Lycatab® PGS.
  • the amount should be chosen in such a way as to provide a soft, smooth, silky, non-sticky, non-slimy and easy-to-swallow formulation when combined with the ibuprofen particles and the other excipients and ingested orally; i.e. the viscosity increase should be moderate and e.g. not lead to the compositions sticking to the tongue surface.
  • the sugar or sugar alcohol is selected from the group of sucrose, maltitol, mannitol, sorbitol, xylitol, and mixtures thereof, such mixtures including e.g. a blend of sorbitol with xylitol or a blend of sorbitol, xylitol and maltitol.
  • the function of such sugar or sugar alcohol is to dissolve in the mouth and help to disperse and swallow the composition, and to provide a tasteful, sweet basis for the composition.
  • citric acid and/or a citrate salt is employed as an acidity regulator as well as a salivation-stimulating agent, and further providing a pleasant balance between sweet and sour tastes as e.g. also found in fruits. Salivation supports the wetting of the composition and dissolution of at least the water-soluble sugar, sugar alcohol or oligosaccharide in the mouth, such that the salivated composition can be swallowed easily.
  • the primary package unit may comprise about 50 mg to 800 mg ibuprofen. This covers the typical range of commercial ibuprofen products which has long been proven to be safe and therapeutically effective. Smaller single doses may be useful for pediatric patients in the treatment of fever and pain, while the larger doses are intended for adults.
  • the pharmaceutical composition comprises spray-granulated ibuprofen particles; at least one hydrophilic polymer selected from pregelatinised starch, xanthan, carmellose-sodium and combinations thereof; and
  • step (i) includes a granulation step and/or a sieving step to obtain the ibuprofen particles of the particle sizes described.
  • a granulation step should not introduce larger amounts (e.g. >10 wt.-% or >5 wt.-% based on the weight of the ibuprofen particles) of excipients, and in particular poorly water-soluble excipients, into the ibuprofen particles, in order to allow for high drug loading and fast onset of effect after consumption of the oral direct composition.
  • Granulation of the ibuprofen raw materials into particles of the sizes described herein may, for instance, involve spray congealing a melt composition comprising at least 90 wt.-%, or at least 93 wt.-%, or at least 95 wt.-%, or at least 96 wt.-%, or at least 97 wt.-%, or at least 98 wt.-%, or at least 99 wt.-% and or even 100 wt.-% ibuprofen.
  • the particle size results are summarised in Table 1; the related aspect ratio values (volume based mean value b/l 3 ) are summarised in Table 2 (up to a cumulative fraction Q3 of 99 %).
  • the particle size distributions are depicted in Figure 1 (cumulative volume fraction Q3 of all particles smaller than a given diameter plotted over the diameter).
  • two of the conventional ibuprofen grades exhibit a fairly narrow particle size distribution, however, the products contain more than 85 wt.-% particles smaller than 150 ⁇ m, more than 65 wt.-% particles smaller than 100 ⁇ m and more than 30 wt.-% smaller than 50 ⁇ m.
  • the ibuprofen obtained from Shasun contains about 35 wt.-% particles smaller than 150 ⁇ m and a very broad particle size distribution.
  • these grades do not fulfil the particle size criteria as required according to the invention. By sieving, of course, the desired particle sizes can be obtained from these materials.
  • Comparative example 1 Oral powder composition with coated ibuprofen
  • Spray-granulated ibuprofen particles (ibuprofen DC 100 by Glatt; see particle size distribution in Table 1) were coated in a hotmelt coating process with a blend of tripalmitin (Dynasan® 116) and polysorbate 65 (Tween® 65) at a ratio of 86:14 to a coating level of 30 wt.-% based on the final weight of coated particles.
  • the coated ibuprofen was then weighed and blended with further components as listed below in a Turbula blender (Willy A. Bachofen AG, Muttenz, Switzerland) until a homogeneous powder mixture was obtained.
  • a single dose of the mixture contained 400 mg of ibuprofen (uncoated).
  • Comparative example 2 Oral powder composition with uncoated ibuprofen and without hydrophilic polymer
